Patented Jan. 14, 1930 ALPHONSE LIPETZ, OF SARATOGA SIRINGS, NEW YORK MOTOR-DRIVING CONNECTION FOR LOCOMOTIVES Application filed August 2, 1928.

This invention relates, generally, to locomotives with electric transmission, and particularly to the driving mechanism thereof, and is an improvementupon that for which the United States No. 1,653,364, were granted and issued to the applicant, Alphonse Lipetz, under date of December 20, 1927.

The object of the invention is to provide readily applicable in connection with driving mechanism having the general characteristic features of that set forth in LettersPatent No. 1,653,- 364 aforesaid, whereby wear may be taken 15 up, as from time to time may become necessary or desirable. j

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 20 1 is a view, half in side elevation and half in vertical section on the line a a of Fig. 2, of the driving mechanism of an electric locomotive, illustrating an application of thein vention; Fig. 2, a vertical transverse section,

25 on the line b b of Fig. 1; Fig. 3, a side view,

in elevation and on an enlarged scale, of one of the power transmitting discs; Fig. 4, a transverse section through the same, on the line 0 c, of Fig. 3; Fig. 5, a partial vertical d cl. of Fig. 1; Fig. 6, a horizontal section on theline e e of Fig. 3; Fig. 7, a view, in vertical section, on the line f of Fig. 8, illustrating a modification of structural detail; Fig. 8, a vertical transverse on the line 9 g of Fig. 7; Fig. 9, a side view, in elevation, of one of the power transmitting discs; Fig.10, a transverse secti'on through the same, on the line h h of Fig. 9; Fig. 11, a partial face view, in elevation, and; Fig. '12, a transverse section through the same on the line '21 i of Fig.11. r

In the practice of the invention, referring descriptively to the specific embodiment thereof which is herein exemplified, and first to Figs. 1 to 6 inclusive, the'mechanism comprehends the following elements, viz; a motor, 6, of any suitable known construction,

which is fixed upon a motor shaft, 10, jour nalled in a housing, 12, secured to the frame,

Serial no. 296,958.

1, of the locomotive, a pair of driving wheels, 7 secured upon an axle, 8; and a gear wheel, 9, mounted on the motor shaft, adjacent to one ofits ends and meshing with a gear wheel, 11. The gear wheel, 11, is located outside of the adjacent driving wheel, and is j ournalled for rotation in the lower end of the housing, 12. Power is transmitted from the gear wheel, 11, to the driving wheels, through a power transmitting disc, 13, which is interposed between the gear wheel and the adjacent driving wheel.

The power transmitting discs are, as in Patent No. 1,653,364 aforesaid, connected with the driving wheels, by pins, 14, projecting from the inner sides of the gear wheels, 11, and fitting in bearings in the discs, 13, and pins, 16, on the confronting faces of the driving wheels, fitting in similar bearings in the discs, there being two pins and their openings in one diameter of each disc, and two pins and their openings located in a diameter at a right angle thereto. The pins 14 and 16, are fitted in spherical bearings, 24, to permit slight angular oscillations in conformity with similar movements of the driving wheels. The pins are mounted for slight radial movement relative to the disc. and capacity for taking up wear due to this movement is provided by fitting said bearings in rectangular blocks, 25, which are mounted, and adjustable radially in, openings, 26, in the power transmitting discs, 13. Adjustment for taking up wear of each block may be effected when desired, by movement of a wedge, 27, interposed between one side of the block and the body of the disc, and having a screw, 28, on its outer end, engaged by an adjusting nut, 29. A shoe, 30, is interposed between the opposite side of the block and the disc.

In order to permit slight oscillations of the members on the tain their proper relation, blocks, 31, are fitted in the confronting sides of the driving wheels and the gear wheels, 11, and are pressed outwardly against the interposed power transmitting discs, by springs, 32.

Figs. 7 to 12inclusive illustrate a modification of Structural detail, which the memline axially therewith; a

bers above described are combined in the same relation, and, without difierence of operative principle, attain the same result by a reversal of the pins, 14*, connecting the power transmitting discs, 13*, with the driving wheels. Such reversal consists in fitting the bearings, 24, in blocks, 25*, in openings, 26 in the adj acentgear, 11, and in the adjacent driving wheel, 7. Adjustment of the blocks is effected by wedges, 27 screws, 28 and nuts,'2'9 as'in the instance first hereinbef'ore described.

While the inventioniis herein exemplified as applied in electric'locomot'ives, it is equally applicable, without departure fromitsioperative principle, in locomotives of other types, as internal combustion engine locomotives, turbinelocomotives, etc, with electric transmission, as well as locomotives with motors ether than electric, such .as hydraulic, pneumatic, etc;
